Duplicate documentation in precipitateEvolution folder

[jpluce]

There are two pdfs files in the precipitateEvolution applications folder, formulation_precipitateEvolution.pdf and precipitateEvolution.pdf. They both appear to have the same roughly the same content, although the commit comments suggest precipitateEvolutioin.pdf is an update to formulation_precipitateEvolution.pdf. To avoid confusion, I would suggest removing one of the pdf files.
