mu T calculator (UC4)

[yucongalicechen]

Problem

UC4

1. user selects "compute muD from known density" radio button
2. labpdfproc.mudCalc presents a form pre-filled with defaults containing fields for user to enter mass density in g/cm^3, composition (e.g. ZrO2), wavelength(angstroms), D (mm). Defaults are <Till's zirconia number>, , , 1.
3. user clicks run calc
4. lpp.mudCalc returns the calculated value as output without running the cve calc.

(originally from comment in #45)

Proposed solution

This seems to be a labpdfproc issue, why is it here?

@yucongalicechen you can close issues here if and when we move them to labpdfproc

I'll make a labpdfproc issue. In your previous comment in #45 you said we might want this funcationality in utils too. Shall I still close it here?
