     * Given an array of parameters passed by the command line, this function
     * searches the specified parameter in that array.
     * For example, if we want the "name" parameter in the following command:
     * $ ./script --name="john" --lastname="doe"
     * this function will return the string "john".
     * There is an option to give aliases for a certain parameter. For example, these
     * commands can be equivalent:
     * $ ./script -n "john" --lastname="doe"
     * $ ./script --name="john" --lastname="doe"
     * $ ./script -n "john" -l "doe"
     * This is done by passing an array to the parameter "name".
     * In the case of "flags", this function returns "true" is the flag is specified,
     * for instance:
     * $ ./script -v
     * $ ./script --verbose
     * This function also detects when several flags are grouped into one, for example:
     * $ ./script -abc
     * instead of
     * $ ./script -a -b -c
     * (this only works with one-character flags)
     * Note that parameter names with more than one character are assumed to be preceded by
     * "--" (like in "--name") parameters with one character are assumed to be preceded by
     * a single "-" (like in "-n")
     *
     * @param array    Array of parameters where we should look
     * @param mixed    A string that specifies the name of the parameter to look for, or an 
     *     array of aliases (ej: array("name", "n"))
     * @param bool Indicate if the parameter MUST have a value associated to it, and that it is
     *    not just a flag. This can also be seen as "isn't a flag" value
