Functions and values

Function or value	Description
`defaultUnitsOfMeasureProvider` Signature: IUnitsOfMeasureProvider
`getInferedTypeFromString(...)` Signature: cultureInfo:CultureInfo -> value:string -> unit:Type option -> InferedType	Infers the type of a simple string value
`inferCollectionType(...)` Signature: allowEmptyValues:bool -> types:seq<InferedType> -> InferedType	Infer the type of the collection based on multiple sample types (group the types by tag, count their multiplicity)
`inferPrimitiveType cultureInfo value` Signature: cultureInfo:CultureInfo -> value:string -> Type	Infers the type of a simple string value Returns one of null\|typeof\|typeof\|typeof\|typeof\|typeof\|typeof\|typeof\|typeof\|typeof\|typeof\|typeof
`parseUnitOfMeasure provider str` Signature: provider:IUnitsOfMeasureProvider -> str:string -> Type option
`subtypeInfered allowEmptyValues ot1 ot2` Signature: allowEmptyValues:bool -> ot1:InferedType -> ot2:InferedType -> InferedType	Find common subtype of two infered types: If the types are both primitive, then we find common subtype of the primitive types If the types are both records, then we union their fields (and mark some as optional) If the types are both collections, then we take subtype of their elements (note we do not generate heterogeneous types in this case!) If one type is the Top type, then we return the other without checking If one of the types is the Null type and the other is not a value type (numbers or booleans, but not string) then we return the other type. Otherwise, we return bottom. The contract that should hold about the function is that given two types with the same `InferedTypeTag`, the result also has the same `InferedTypeTag`.
`supportsUnitsOfMeasure(typ)` Signature: typ:Type -> bool	Checks whether a type supports unit of measure
`typeTag(_arg1)` Signature: _arg1:InferedType -> InferedTypeTag	Returns a tag of a type - a tag represents a 'kind' of type (essentially it describes the different bottom types we have)
`unionCollectionOrder order1 order2` Signature: order1:InferedTypeTag list -> order2:InferedTypeTag list -> InferedTypeTag list
`unionRecordTypes allowEmptyValues t1 t2` Signature: allowEmptyValues:bool -> t1:InferedProperty list -> t2:InferedProperty list -> InferedProperty list	Get the union of record types (merge their properties) This matches the corresponding members and marks them as `Optional` if one may be missing. It also returns subtype of their types.
