 =====invert.c===== =====invert.c=====
 +A bit-wise inversion is an operation where the end outputs the opposite bit of the beginning input. What this means is that the input bit of 1 will result in a 0 after this operation.  
 +Example of outputs and error messages:
 +<code>
 +./invert -s "10011010 11010001" -->  01100101 00101110
 +</code>
 +<code>
 +echo "1100101100011101" | ./invert --> 0011010011100010
 +</code>
 +<code>
 +echo "1000100" | ./invert -B --> 0111011
 +</code>
 +<code>
 +echo "12" | ./invert -B --> invalid number!
 +</code>
 +<code>
 +./invert -V --> 0.0.2
 +</code>
 +<code>
 +./invert --help
 +Usage: ./invert [OPTION]... [FILE]...
 +performs a bit inversion against a set of input values!
  
 +Arguments:
 + -h, --help             display usage information
 + -V, --Version          display version information
 + -s,  -string           specify STRING as value to process
 + -v,  -verbose          displays more information to STDOUT
 + -d,  -delimiter        use the argument as a delimiter
 + -q,  -quiet            do not display anything to STDOUT
 + -B,  -Binary           input data is to be considered as binary
 + -O,  -Octal            input data is to be considered as octal
 + -D,  -Decimal          input data is to be considered as decimal
 + -H,  -Hexadecimal      input data is to be considered as hexadecimal
