Detailed Description
template<int spacedim, class Value>
class MultiField< spacedim, Value >
Class for representation of a vector of fields of the same physical quantity.
When solving a system of same equations with the number of components given at runtime (as in the case of transport equation for runtime given number of substances) we need means how to work with the whole vector of fields at once. This is the aim of this class. It provides the interface given by the parent class FieldCommonBase, but principally it is just a vector of Field<Value,dim> objects. The sub-fields or components of a MultiField are independent objects, how ever the setters propagates the values from the MultiFields to the individual fields. The only exception is the set_name method which in conjunction with MultiField::set_subfield_names can set unique name to each component.
Template parameters are used for every subfield.
TODO:
- general mechanism how to convert a Field< dim, Vector> to MultiField< dim, Value>
- implement set_from_input
- implement set_Time
- problem with "input" methods, since Field works with AbstratRecord, the MultiField - However - should use Array of AbstractRecords simplest solution - test that in EqDataBase and have more methods in FieldCommonBase, or somehow detach input handling from Fields
Definition of MultiField must be in separate file. In other case source file field.cc is too big and compiler can throw compile error.

Polymorphic copy. Check correct type, allows copy of MultiField or Field.

overridevirtual |
Returns input type of particular field instance, this is usually static member input_type of the corresponding FieldBase class ( with same template parameters), however, for fields returning "Enum" we have to create whole unique Input::Type hierarchy for every instance since every such field use different Selection for initialization, even if all returns just unsigned int.

Returns input type for MultiField instance. TODO: temporary solution, see multifield_

We have to override the set_mesh method in order to call set_mesh method for subfields.
Reimplemented from FieldCommon.

Abstract method to update field to the new time level. Implemented by in class template Field<...>.
Return true if the value of the field was changed on some region. The returned value is also stored in changed_during_set_time data member.
In first call initialize MultiField to the number of components given by the size of names and use this vector to name individual components. Should be called after the setters derived from FieldCommonBase.
Implements FieldCommon.

| void MultiField< spacedim, Value >::set_up_components | ( | ) |
Initialize components of MultiField.
Must be call after setting components, mesh and limit side.

inline |
Number of subfields that compose the multi-field.
