Ok, I finally manage to read Python code from my file. I checked current
working directory in my plugin code and it happens to be Maya installation
folder which is not ideal but for now it will suffice.
I guess I should use MEL getenv MAYA_PLUG_IN_PATH command and extract some
absolute path where my plugin will be installed.
