/**
 * Data model for VersionSpecifications (for Evergreen).
 *
 * A VersionSpecification models a 'rule' by which a host making a query to Evergreen may be matched to a VersionSet
 * for purposes of specifying the correct packages-versions that should be installed on the host. The VersionSpecifications
 * form a total order via the `next` attribute (i.e. ordered via the linked-list method).
 *
 * A VersionSpecification is said to match a host if and only if each of the
 * VersionSpecificationAttributes match the corresponding qproperty provided by the host.
 *
 * Currently, there is no support for domains or separate groups of VersionSpecifications.
