Adding parserMRC

[emilysperanza]

Added ability to view .mrc and .st file formats: http://bio3d.colorado.edu/imod/doc/mrc_format.txt .mrc is the standard file format for viewing electron microscopy tomography data.

Did you try to compile it?

It looks like there are some issues:

• indentation in loader.js is incorrect
• some indentation in parserMRC is incorrect
• parseInt( number ) should be parseInt(number, 10) in parserMRC
• filpEndianness typo - code not working. Should we just get rid of it for now?

Could you please re-submit a new patch?

Thanks

New Patch: We have compiled the code and it has worked.
I fixed the indentation problems and removed the lines with the typo.
