using #ocr as stated in README results in input error

[jspillers]

the following code:

client = Rubix.new(access_token)
client.ocr(remote_file_url: url)

results in this not super helpful error... recommend wrapping this error and returning something more descriptive

/Users/<user>/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/rubix-api-0.0.2/lib/rubix.rb:76:in `rescue in error_handler': 757: unexpected token at 'flag ocr needs at least one value (Rubix::ParseError)
input error!

for help use -help (duh!)
ocr, lanscape and histogram arguments
-s <path to scene file> : scene file refers to the image that will be tested
-S <path to scene folder> : will test all images inside a folder
-p <path to patterns folder> : patterns refer to images againts a scene will be tested

ocr, landscape and face common arguments
-show : this enables UI output
   * when doing ocr detection this will show the input image and a green rectangle for each rectangle passed as argument
   * when doing landscape detection this will show the histogram constructed from the patterns images with min, max and avg values
   * when doing face detection this will show main and details features detected

histogram, landscape common arguments
-min <value> : this will set the minimum accepted value when testing a scene
   * when doing histogram matching this value will refer to the minimum matching pertentage
     the scene and pattern histograms must have to be a succesfull match
   * when doing landscape matching this value will refer to the minimum percentage the values of the scene histogram matches the landscape histogram
       * if the matching use the min max values of the landscape histogram then a scene histogram value match if it's between the corresponding
         lanscape min and max value
       * if the matching use the avg values of the landscape histogram then a scene histogram value match if it's equal to the corresponding
         landscape histogram avg value

template specific arguments
-mma <value> : this will set the minimum matches a pair of scene/pattern must have to be a succesfull match
-mr <min ratio> : filter matches where the distance ratio between nearest matches is greater than min ratio

histogram specific arguments
-corr : will use correlation method when comparing histograms
-inter : will use intersection method when comparing histograms

landscape specific arguments
-minMax(default value) : this will use the min values and max values of the histograms of the landscapes
-avg : this will use the average value of the landscapes histograms
-safeOffset <value> : when comparing histogram value x this will also compare with x+value and x-value
   *when using min max values of the landscapes histogram, an x value from the scene histogram will match if x is in [min-value..max+value]
   *when using average values of the landscapes histogram, an x value from the scene histogram will match if x is in [avg-value..avg+value]
-label <value> : this will set the landscape label to value
-color : will use color to make landscape and scene histograms
-gray : will use gray to make landscape and scene histograms
-hsv : will use hue and saturation to make landscape and scene histograms
   NOTE: if there's neither -color, -gray or -hsv specified then the matching will be made using all three and taking the max value for each

ocr specific arguments
-rois <p1x p1y p2x p2y>+ : will define rectangles in which ocr recognition will be executed
-mode <0-3> :  sets which engine to use
   OEM_TESSERACT_ONLY(0)          : Run Tesseract only - fastest
   OEM_CUBE_ONLY(1)               : Run Cube only - better accuracy, but slower
   OEM_TESSERACT_CUBE_COMBINED(2) : Run both and combine results - best accuracy
   OEM_DEFAULT(3)                 : Specify this mode when calling init_*(),
                                    to indicate that any of the above modes
                                    should be automatically inferred from the
                                    variables in the language-specific config,
                                    command-line configs, or if not specified
                                    in any of the above should be set to the
                                    default OEM_TESSERACT_ONLY.
-datapath <path> : the location of tessdata folder containing the trained data files
-lang <[~]<lang_value>[+[~]<lang_value>]*> : sets the languages to use, ~ is used to override the loading of a language
-clearEvery <times> : will clear tesseract memory every times recognitions


template matching
./anakin2 (-s <value>|-S <value>) -p <value> [template matching arguments]


histogram matching
./anakin2 (-s <value>|-S <value>) -p <value> (-h | -hColor | -hHSV | -hGray) [histogram matching arguments]
-hColor : will use color histograms for matching
-hGray : will use gray histograms for matching
-hHSV : will use hue and saturation histograms for matching
-h : will use all of the above histograms and use the maximum value obtained for matching


landscape matching
./anakin2 -landscape (-s <value>|-S <value>) -p <value> [landscape matching arguments]


ocr detection
./anakin2 -ocr <path to image> [ocr arguments]


ocr basic demo
./anakin2 -ocrDemo


ocr advanced demo
./anakin2 -ocrAdvDemo


face detection
./anakin2 -face <path to image> -mainCC <path to xml> [-detailsCC <path to xml>+] [-scaleFactor <value> -minNeighbors <value> -minSize <value> -maxSize <value>]
-face <path to image> : will use face detection on the specified image
-mainCC <path to xml> : the classifier file used to detect main features
-detailsCC <path to xml>+ : classifier fiels used to detect details inside detected main features
-scaleFactor <value> : specify how much the image size is reduced at each image scale.(default 1.1)
-minNeighbors <value> :  specify how many neighbors each candidate rectangle should have to retain it.(default 3)
-minSize <width> <height> : minimum possible object size. Objects smaller than that are ignored.(default none)
-maxSize <width> <height> : Maximum possible object size. Objects larger than that are ignored.(default none)

NOTE: the order of the arguments doesn't matter (it only matters the order -flag [<values>])
