add google-simplified.mustache and sphinx-simplified.mustache

[johnjim0816]

I delete extra blank lines for google format and save as "google-simplied", so that it seems look like better at least for me. An example in python shown as following:
'''[summary]
Args:
init_status ([type]): [description]
aim_status ([type]): [description]
x_width ([type]): [description]
y_width ([type]): [description]
Returns:
[type]: [description]
'''
And also for sphinx:
'''[summary]
:param init_status: ([type]): [description]
:param aim_status: ([type]): [description]
:param x_width: ([type]): [description]
:param y_width: ([type]): [description]
:return: ([type]): [description]
'''
