Strip pdf/text into strings
args in: {file_name, type = 'file_type', delete = [], start = [], end = [], both = [], lower_case = Bool}
file_name: Name of the file with extension as string
path : only specify if the file is in a different directory, input as string
type : 'txt' or 'pdf'
delete : Removes the char everywhere in the string_list
start : Removes the char at the start of string_list but not everywhere
end : Removes the char at the end of string_list but not everywhere
both : Removes the char at either ends. If both is defined, start and end lists are redundant
lower_case: Boolean input for forcing all chars to lower case; True by default
No packages required unless you wish to parse strings from pdf, then the only requirement is the package 'tika'
Note: tika requires java 7+ to run
Errors while running tika: Make sure that Java version 7+ is installed, added to path variable and PC restarted once Java is installed
