Your task is to read a file containing lines of text, and to write another file that contains these lines, where all vowels (both uppercase and lowercase) are replaced by underscores. For example, if your input file just contains the lines:

Mary had a little lamb, 
its fleece was white as snow.

then your output file should contain the lines:

M_ry h_d _ l_ttl_ l_mb,
_ts fl__c_ w_s wh_t_ _s sn_w.
