Release/7.0

[tnunnink]

This release improves TagName and Instruction text parsing to correctly capture and extract nested indirect tag references found in arrays. This is accomplished by moving away from Regex pattern matching to new NeutralText and NeutralStream lexer/tokenization pattern.

New classes that can be used to stream tokens from a string of neutral text include.

• NeutralText: This is a light wrapper around a string that provides the ability to tokenize the string.
• NeutralToken: This is a single token in the stream of natural text. It contains the token type, value, starting index, and length.
• TokenType: This is an enumeration on the token class that indicates the type of the token (Identifier, Literal, Bracket, Dot, Parenthesis, Comma, etc.).
• NeutralStream: This is a stream interface for enumerating a sequence of tokens for processing.

I have also updated the API for TagName to make the properties a little more explicit.

• Path > FullPath
• LocalPath (same)
• Operand > RelativePath
• Member > MemberPath
• Base > BaseName
• Element > MemberName

Argument has also been simplified. It now mostly centers around identification of the argument value (reference, literal, expression, etc). It is now up to user to determine if an argument needs to be parsed further (expression case). This can be done by using TagName.Parse static method to extract tag names from the argument expression if needed.

Instruction was also updated to just provide the main Arguments collection since you can filter arguments by type. I think this simplifies the API a bit as it was already getting a little confusing and circular.
