## FUNCTIONS
* Calculate read N50 from a set of lengths `get_N50(readlenghts)`  
* Remove extreme length outliers from a dataset `remove_length_outliers(dataframe, columname)`  
* Calculate the average Phred quality of a read `ave_qual(qualscores)`  
* Write out the statistics report after calling readstats function `write_stats(dataframe, outputname)`  
* Compute a number of statistics, return a dictionary `calc_read_stats(dataframe)`
