Lab #5: Implementing numerical data requirements

JSON instances are to contain a latitude value.
The value must be in decimal format,
must be between -90 and +90, must have
exactly two digits to the right of the decimal 
point, and there must be at least one digit to
the left of the decimal point. Here is a valid 
latitude value:

	74.23

How will you express these data requirements using
JSON Schema? Go ahead and implement the data
requirements (using JSON Schema, of course).

Validate using the online validator tool.

Test your JSON Schema using both bad and good data.

Remember to use anchors in regular expressions!
