setParameter feature of the IValidate::AddService method

There are 2 service providers in swissDRG -hospitals and maternity clinics- using the same service code space! Furthermore, swissDRG distinguishes between normal and relocation cases.
For being able to separate these cases, pseudo services have been defined consisting of a tariff type, a date and a pseudo code! Such a pseudo code consists of:

setParameter(cmd=value)

where the whole pseudo code is case and whitespace insensitive. A pseudo code is active until the next call of the Initialize method and is then reset to the default values.

The following pseudo codes are defined for swissDRG:

1. setParameter(providerType=value), with value = { hospital | maternityClinic }, and hospital as default.
   This command set the focus to swissDRG service records for hospitals or maternity clinics, respectively.
2. setParameter(relocation=value), with value = { on | off }, and off as default.
   This command calculates the TP for the normal (off) or relocation (on) case.

The return value of AddService is S_OK for successfully set a pseudo value. However, do not call the properties as these are undefined in such a case.
