The invention claimed is: 1. A level for measuring, comprising: a level body having a recess; a vial positioned within said recess and secured to said level body; a resilient foam positioned between a lower surface of said vial and an interior surface of said level body to act as a resilient support to said vial; and a cover configured to engage an upper surface of said vial, said cover being secured to said level body. 2. A level according to claim 1, wherein said level body has a top and a bottom, said bottom having a generally V-shaped cross-section, and said recess extends through said top. 3. A level according to claim 1, wherein said resilient foam is formed as a preformed layer that is positioned between said vial and said level body. 4. A level according to claim 1, wherein said cover is secured to said level body by fasteners. 5. A method of installing a vial in a level, comprising: positioning a resilient member in an opening in the level on an interior surface of the level; positioning the vial within the opening while forcing the vial against the resilient member; engaging a cover with an upper surface of the vial; securing the cover to the level; adjusting the position of the vial within the opening by adjusting the cover, wherein the resilient member resiliently accommodates the adjusting; and securing the vial in the adjusted position. 6. A method according to claim 5, wherein the positioning the resilient member includes positioning a foam layer within the opening. 7. A method according to claim 5, wherein the adjusting the position of the vial includes initially securing the cover with a fastener and then adjusting the position of the vial by adjusting the fastener. 8. A method according to claim 5, wherein the securing the vial includes applying an adhesive within the opening in the level and adjusting the position of the vial before the adhesive sets and secures the vial in the adjusted position. 9. A level for measuring, comprising: a level body having an opening; a resilient member positioned in said opening; a vial having an upper surface and a lower surface, the vial positioned within said opening and the lower surface of the vial forced against said resilient member by a cover configured to contact the upper surface and an adjustable device that is configured to adjust the position of said vial within said opening while said resilient member contacts said vial and resiliently accommodates the adjusting; and a securing element configured to secure said vial in the adjusted position relative to said level body. 10. A level according to claim 9, wherein said securing element is an adhesive. 11. A level according to claim 10, wherein said resilient member is formed from a non-metallic structure. 12. A level according to claim 10, wherein said resilient member is foam. 13. A level according to claim 10, wherein said adjustable device is a threaded fastener.
