Test how RedBeanPHP OODB and OODBBean handle type and type casts.
Rules:
1. before storing a bean all types are preserved except booleans (they are converted to STRINGS '0' or '1')
2. after store-reload all bean property values are STRINGS or NULL
(or ARRAYS but that's only from a user perspective because these are lazy loaded)
3. the ID returned by store() is an INTEGER (if possible; on 32 bit systems overflowing values will be cast to STRINGS!)
After loading:
ALL VALUES EXCEPT NULL -> STRING
NULL -> NULL
