Removed statistical tests

Previous version did not account for multiple testing in binomial test,
had to be removed. Code not working, issue with strand information.
Now works without doing binomial test on each mC

Changed from statistical test to %mC at each position (don’t need to
correct for multiple testing). Removed summary files, dictionaries now
to file using pickle.
Fixed case where mC at first base of gene feature

When mC at first base of gene (0% along gene), caused error. Changed
functions to merge dictionaries. Still need to adjust relative
locations graph and subtract nonconversion rate.
Corrected tally function to compute total mC

Function was computing average mC level rather than total for relative
location plots.
Fixed error when position at end on feature

Removed unnecessary imports, cleaned up code a little.
Added intron info

Added intron methylation info to plots. Changed to 2 kb up/downstream.
Added information for transposons

Added transposons to total methylation bar charts
Added plots for TEs

added separate line plots for TE body +/- 2 kb
