Need to update the Matplotlib requirements

[DDubbleDD]

Was going to try this out today but could not get installed. PIP was trying to install an old version of Matplotlib (2.0.0) which gave this error.
"freetype: no [The C/C++ header for freetype
(freetype2\ft2build.h) could not be found. You may
need to install the development package.]
png: no [The C/C++ header for png (png.h) could not be
found. You may need to install the development
package.]
