Python pathsetting

If you have the following error message after installing python and trying to run python or pip or the install_psychopy.bat, the path environmental variable hasn't been set correctly during the python installation process.

To set up the environmental variable "Path" correctly, follow instructions from the links below, depending on which version of windows (win7 or win10) your system is:

win10

In both cases, note that the path to append to the end of the existing path string is ";C:\Python27;C:\Python27\Scripts" (without the quote).
