Return user input, after validating it against arbitrary criteria.
The user input must satisfy all conditions in conditions_all, and one
or more of the conditions in conditions_any. Conditions_any is a list,
with the first item the error string to display if none of the conditions
are met. Conditions_all is a list of tuples, with each tuple having one
condition + the associated error string to display to the user if the
condition is not met.
The conditions will be inserted in 'if' statements, and must be
written so that the 'if' statement will be true if the data is valid.
E.g.
if a 'Q' is needed: 'X == "Q"'
Note 1: all data input by the user is seen as a string, even if
numbers are entered. If the test is looking for an integer, write it as:
'int(X)'
Note 2: All tests are run inside 'try' statements, so exceptions will
not cause problems. Any test that raises an exception is treated as a
failed test.
Note 3: One idiosyncrasy of 'if' statements is that any statement that
returns a "0" is treated as a False. Tests must be crafted so
a pass does not return a '0'. E.g., if the test is intended to check
that the data is a float, and a zero would be valid data, do not write
the test as: 'float(X)', as 'if float("0"):' will not pass.
