Mark id and lastUpdated as nullable (closes #24)

Also indicate that these contact attributes should be initialized to
null when a contact is created.
Use a String enumeration for Contact gender (closes #21)

Also rename "sex" attribute to "gender" as this is more consistent
with vCard format.
Remove default value for id and lastUpdated attributes.

Those will be documented in the Contact constructor algorithm.
Have remove() method take a contact identifier in argument (closes #9)

The remove() method was previously taking a Contact object in argument,
which is not needed and inconsistent with other specifications.
Use plural form for attributes of array type (closes #20)

Also partially addresses issue #15.
