First commit removing the integer number type. This should

remove some complexity and unexpected behavior around numbers in
general as all numbers are the same number type, IEEE 754 double
precision numbers. Also update examples and tests, some of which were
out of date.

Some more testing may be needed for new changes to numbers.
