Fix precedence of interval operator
...
The interval operator has a lower precedence than, for example, binary
operations. This was unexpected and incorrectly implemented in the
output functions. For now, this is fixed by enclosing intervals in
parentheses to avoid misinterpretations.
The existing unit tests are adjusted to the updated output format.

Remove unnecessary parentheses
...
The unary modulus operation does not require extra parentheses to be
printed in cases like “|X + Y|”. This adds a new option to the printing
routine to omit parentheses in cases where the parent expression already
defines a parenthesis-like scope (currently only with unary operations).

Support modulus operation (absolute value)
...
This adds support for computing the absolute value of a term along with
an according unit test.
