Cache stores live information about project storage which has not yet been synced to ProjectAccounting.

All the implementations must follow the convention of returning errors of one of the classes defined in this package.

All the methods return:

ErrInvalidArgument: an implementation may return if some parameter contain a value which isn't accepted, nonetheless, not all the implementations impose the same constraints on them.

ErrSystemOrNetError: any method will return this if there is an error with the underlining system or the network.

ErrKeyNotFound: returned when a key is not found.

ErrUnexpectedValue: returned when a key or value stored in the underlying system isn't of the expected format or type according the business domain.
