title: Import forked module in Python instead of installed module
body: <p>I would like to make changes (and possibly contribute if its any good) to a public project on GitHub.  I've forked and cloned the module but Im unclear how to get my program to import the local library instead of the 'official' installed module.</p>
  
  <p>I tried cloning it into my project folder but when I imported it and tried to use it things got weird <code>calmap\calmap.plot()</code></p>
  
  <p>I also tried doing <code>sys.path.append</code> and the folder location.  But it seems to still import the official one instead of the forked.</p>
  
  <p>I'm assuming that I could put my program inside the module folder so that module would be found first but I can't image thats the 'correct' way to do it.</p>
